Odd badges

Here's a few badges from my collection. The Essex Regiment (Tank) badges are as follows: frosted silver officer's badge, brass badge, copper badge and the usual white metal. Bottom row, the CAFVS badge, an Armoured Corps badge without the voids around the tank and a copper RCAC badge. The copper badges and the CAC badge without the voids are unusual and I haven't found them in any reference books. Thought you guys might like to see them.

Hi sarge, The Essex Regt Tank in brass has been repro'd. Check out this the thread about them on the B&CMBF, http://www.britishbadgeforum.com/forums/showthread.php?t=6761&highlight=essex+regiment+tank.The RCAC badge was not made in copper. There have been some of these "recovered" from disposal. They were buried and are corroded by ground chemicals. They may look like copper. Could you give a close up image?

Hi sarge, That is a "dug" badge. RCOC used to dispose of obsolete badges by burying them. With the advent of metal detectors, several caches have been found. When buried the chemicals in the soil corrode and leach into the metals, changing their colour and pitting the surface. The RCAC is a classic example of the effects of being buried.
